Kangaroo Island's community and tourism industry will be jeopardised if federal Environment Minister Greg Hunt fails to block seismic testing off the coast, says Australian Greens Senator for South Australia Penny Wright.

The Weatherill Government must refuse to adopt Prime Minister Abbott's plan to gut national environment protection at COAG tomorrow, says Australian Greens Senator for South Australia Senator Penny Wright.

Federal Labor representatives voted with the Greens yesterday to call on the Weatherill Government to reject the move.

"Tony Abbott wants to take away a 30-year-old federal veto power to protect our most precious wildlife and wilderness," South Australian Greens Senator, Penny Wright, said.
